A flexible substrate bonding and debonding apparatus is disclosed. In one embodiment, the apparatus includes i) a chamber, ii) a lower chuck disposed in a lower portion of the chamber and having a lower heating unit and a cooling conduit built therein, iii) an upper chuck disposed above the lower chuck and having an upper heating unit built therein, iv) a pressurizing unit disposed above the upper chuck and v) a separating unit corresponding to either side of bonding surfaces of a support substrate and a flexible substrate which are disposed between the lower chuck and the upper chuck. The flexible substrate bonding and debonding apparatus can pressurize the flexible substrate and the support substrate simultaneously using a heat-treatment process. Therefore, the flexible substrate can be more reliably bonded and debonded even at low temperature.
